Specification of Letterslatent ltfo. 8,242 dated Ju1y 2 2, 1851 To allwhom, it may concern Be it known that, I, N. A. BOYNTON, of Boston, inthe county of Suffolk and State of Massachusetts, have invented certainnew and useful Improvements in Parlor Cook ing-Stoves, and thatthefollowing description, taken in connection with the accompanyingdrawings, hereinafter referred to, forms a full and exact specificationof the same, wherein I have set forth the nature and principlesfof mysaid improvements, by which my invention may be distinguished fromothers of a similar class, together with such parts as I claim anddesire to have secured to me by Letters Patent."

My improvements consist in the arrangement of fines about the oven, bywhich the heat, smoke, &c.,lis.made to pass about both the sides and thetop and bottom of said oven, the end or partof the oven most remote fromthe fire chamber, being heated as well as the part adjacent to said firechamber. p The accompanying plates of drawings represent myimprovements.

In Plate- 1, Figure 1, is a elevation of my improved stove.

front or end Fig. 2 is a plan or top view of the same. In Plate 2, Fig.3, is a transverse verticalsection taken;

in the plane of. the line A-B, Fig. 2,Plate 1, and Fi 4 is alongitudinal vertical section taken in the plane of the line C in said IFig. 2.

a a a in Fig. 4 Plate 2 represents the fire chamber with a swinginggrate 6 band having directly under it the ash pit 0 0, cl and 6 beingrespectively thefire chamber and ash pitoloors. At the top, of one ofthesides of the fire chamber, is an aperture through c which the smoke,&o., passes intothe smoke pipe f, while the fireis being kindled, saidaperture, at. other times, being closed bythe sliding damper g, shown inFig. t Plate 2. In the topplate h l of the stove, is formed the apertureor; spaced, to be used for boiling purposes. Immediately behind the firechamber and between the partition/hi0 on the back of said fire chamberandthe rear end plate Z Z of the stove, is placed the oven m m m 'm,said partition in k which extends a little way overthe top of the oven,forming the back of the oven, and said ovenjbea ing supported byflangesformed on the back of the partition and by a flange on the rear endplate Z 'Z. In this end plate Z Z isthe oven door 11. n. I l c .7: 7c,is prevented from passing immediately across the top of the oven outthrough the smoke pipe, by the partition 1), extending in a diagonaldirection from the top of the oven to the top of the chamber which leadsto the smoke pipe, as shown in Fig. 3

Plate 2.

A curved partition w extends from the top plate h h to the top of theoven, as shown in Fig. 3 Plate-2 and by dotted lines in Fig. 2 Plate 1,and abuts against the partition is is. From the bottom plate 39 p, ofthe stove, extends the long straight partition as w to the bottom of theoven, running nearly the whole length of said oven; "The course of theheat, &c., is shown by the arrows in the drawi gs.

As the heat comes up from the fuel into the chamber 0 0 on the top ofthe oven, it is prevented from passing directly into the chamber t t onthe side of the oven, by the curved partition W, before referred to, bywhich means it is made to traverse the whole top of the oven, before it.can pass into the chambert 25, thus keeping the part of the oven remotefrom the fire chamber hot, as wellas the part adjacent; to said firechamber. It then passesidown the passage t 25 into the passage 9 9 underthe oven, and is made-"topassto the end of the oven which is farthestfrom the fire chamber, before .it

tition w m; From the passage q 9 it passes up through the passage 11. uand out through the smoke pipe, thus forming a current of heatentirely'around the top, bottom and both sides of the oven. a

c Having thus describedmy improvements in parlor cookingstoves, I shallstate my claim as follows.

. What I claim as my invention and desire ing stove, by which the heat,smoke, &c., is first made to pass over the top of the oven and then dOWnthe passage formed between the front side plate and the side of theoven, a'cross the bottom of the oven up through the passage formedbetween the rear side plate and the other side of the oven, and finallyout through the smoke pipe; the heat, &c., being made to pass to thepart of the oven most remote from the fire chamber, by the N. A.BOYNTON.
